Question

Complete the following tables. $y=-2x+4$ $x$$1$$3$$5$ $y$$2$$-2$ $2x-y=12$ $x$$3$$4$$5$ $y$$-6$$-2$ Draw the $2$ graphs on the grid given below. Hence, solve the simultaneous equations $y=-2x+4$ and $2x-y=12$.

Accepted Answer

(a)(i) $-6$ (ii) $-4$ (b) the graphs intersect at $(4,-4)$, so $x=4,\ y=-4$
